Abstract :Accompany with the development of our national economic , high buildings are increasing and cent ral air2conditioning is popularized quickly , and the energy problem has become more apparent . Aimed at the cent ral air2conditioning air supply system has high power consumption and serious waste of energy , based on the formed system the possibility of using converter and closed2loop cont rol to t ransformation the system was analyzed , and the specific rehabilitation project and cont roller circuit was proposed.Key words :cent ral air2conditioning ;energy2saving ;air supply system; converter
